A command-line wrapper for the NSS UDP Speed Test kernel module on OpenWrt systems.

• Single command operation for UDP speed tests
• JSON formatted output
• Automatic resource cleanup
• Integration with NSS UDP Speed Test kernel module
• on sait pas trop ce qu'on va ajouter

The package can be installed on OpenWrt 23.05 using opkg:

opkg update
opkg install linksys-udp-st

The utility provides three main commands:

linksys-udp-st start --src-ip <source_ip> --dst-ip <destination_ip> \
                     --src-port <source_port> --dst-port <destination_port> \
                     --protocol <tcp|udp> --direction <upstream|downstream>

This will:

• Load the kernel module
• Configure the test parameters
• Start the speed test
• Run for 20 seconds by default

linksys-udp-st status

Returns JSON output with:

• Current test status (idle/running/completed/failed)
• Current throughput (if test is running)

linksys-udp-st stop

This will:

• Stop the current test
• Output final results in JSON format
• Unload the kernel module
• Clean up resources

To start a UDP speed test, use this command:

linksys-udp-st start --src-ip 192.168.1.144 --dst-ip 192.168.1.64 --src-port 5201 --dst-port 5201 --protocol udp --direction upstream

• --src-ip: Source IP address (sender)
  • For upstream tests: your local device's IP
  • For downstream tests: the remote device's IP
• --dst-ip: Destination IP address (receiver)
  • For upstream tests: the remote device's IP
  • For downstream tests: your local device's IP
• --src-port: Source port number (typically 5201)
• --dst-port: Destination port number (typically 5201)
• --protocol: Either 'udp' or 'tcp'
• --direction: Either 'upstream' or 'downstream'

1. Testing Upload Speed (Upstream):

linksys-udp-st start \
    --src-ip 192.168.1.144 \  # Your local device
    --dst-ip 192.168.1.64 \   # Remote device
    --src-port 5201 \
    --dst-port 5201 \
    --protocol udp \
    --direction upstream

2. Testing Download Speed (Downstream):

linksys-udp-st start \
    --src-ip 192.168.1.64 \   # Remote device
    --dst-ip 192.168.1.144 \  # Your local device
    --src-port 5201 \
    --dst-port 5201 \
    --protocol udp \
    --direction downstream

Status check while running:

{
    "status": "running",
    "throughput": 1000000000,
    "unit": "bps"
}

Final results:

{
    "test_config": {
        "src_ip": "192.168.1.100",
        "dst_ip": "192.168.1.200",
        "src_port": 5201,
        "dst_port": 5201,
        "protocol": "udp",
        "direction": "upstream"
    },
    "results": {
        "throughput": 1000000000,
        "unit": "bps"
    }
}
